> he costs of removable batteries to address these really niche use cases

You seem to have completely missed the primary point of all this, which is to reducew ewaste. That fact that it also satisfies some niche uses cases is a great bonus!

External battery banks are a better reducer of e-waste as they'll work for all devices and not just the one cell phone.

Everyone acting like iPhones and mainstream Android phones become e-waste after 3 years is just making specious arguments.

Why does the average phone user know more about phone batteries and replacing them than all of these commenters acting like iPhones are becoming e-waste after a couple years?

I think I know more people with 4-6 year old iPhones than with an iPhone 17.

Apple stores will replace the battery for you for a very reasonable fee and the phone will carry on for many years more. This is a common thing to do and you can find battery replacement services for popular Android phones too.
